TECHNICAL FIELD

This document relates generally to the motor vehicle equipment field and, more particularly, to a hood assembly incorporating a fluid reservoir as well as to a fluid reservoir having a body including a stringer section and a plurality of finger sections.

BACKGROUND

For many years now, motor vehicle manufacturers have equipped motor vehicles with a washer fluid reservoir that stores washer fluid for cleaning the windshield of a motor vehicle. Such a reservoir may also be utilized to clean the headlamps on some motor vehicles.

Such a washer fluid reservoir occupies useful space in an already crowded engine compartment. This document relates to a hood assembly that incorporates the washer fluid reservoir. More specifically, the washer fluid reservoir is carried against the inner surface of the hood shell. Such a reservoir is thin enough so as to not intrude substantially into the engine compartment. Further, the fluid reservoir has a body that is shaped to minimize the production of waves during motor vehicle operation and thereby reduce the sloshing of fluid in the washer reservoir.

DETAILED DESCRIPTION

Reference is now made to FIG. 1 illustrating a first embodiment of the hood assembly 10 that is mounted by means of a hinge assembly (not shown) to the motor vehicle 12. As illustrated in FIG. 1, the hood assembly 10 is in a raised position.

The hood assembly 10 includes a hood shell 14. The hood shell 14 may be stamped from a sheet metal material. When the hood assembly 10 is closed, the hood shell 14 functions as a cover for the engine bay 16 while providing aerodynamic benefits, structural integrity and design appeal to the motor vehicle 12.

The hood assembly 10 also includes a fluid reservoir 18. In the illustrated embodiment, the fluid reservoir 18 is designed to hold washer fluid.

In the embodiment illustrated in FIGS. 1, 1 a and 3, the fluid reservoir 18 has a body 20 that includes a stringer section 22. A plurality of finger sections 24 are connected to and extend from the stringer section 22. Here it should be appreciated that the body 20 defines a fluid retention cavity 26 that extends uninterrupted through the stringer section 22 and the plurality of finger sections 24.

A washer fluid pump 28 is carried on the hood shell 14. The washer fluid pump 28 functions to pump washer fluid from the fluid retention cavity 26 in the fluid reservoir 18 through the feed lines 30 to the spray jets 32 which direct that washer fluid onto the windshield 34 of the motor vehicle 12 when an operator desires to clean the windshield. This may be done by manipulating an appropriate actuator (not shown) in the motor vehicle passenger compartment in a manner known in the art.

As best illustrated in FIGS. 1 and 1 a, the fluid reservoir 18 includes a filler port wall 36 that forms a fill port or fill spout 38. A removable cap 40 closes the fill port 38. In the embodiment illustrated in FIG. 1a , the fill port 38 opens toward the hood shell 14. The hood shell 14 includes a filler door 42 connected by means of a hinge assembly 44 to the hood shell.

When one wishes to add washer fluid to the fluid reservoir 18, one opens the filler door 42 as illustrated in FIG. 1a . Next, the individual removes the removable cap 40 from the filler port wall 36 in order to open the fill port 38. Fluid is then poured into the fill port 38 when the hood 10 is in the raised position illustrated in FIG. 1. That fluid then flows by gravity, filling the stringer section 22 and the finger sections 24. After filling with washer fluid, the removable cap 40 is again secured on the filler port wall 36 and secured in position so as to close the fill port 38. The connection between the removable cap 40 and the filler port wall 36 may be by means of cooperating threads or other appropriate means.

As further illustrated in FIG. 1a , the hood assembly 10 may also include an insulation layer 46. That insulation layer 46 may be made from any appropriate material having sound and/or temperature insulating properties. As illustrated, the fluid reservoir 18 is packaged between the hood shell 14 and the insulation layer 46.

In an alternative embodiment illustrated in FIG. 2, the filler port wall 36 extends through the insulation layer 46 at the rear of the hood shell 14. When the hood assembly 10 is raised as illustrated in FIG. 2, the removable cap 40 is easily accessible. Once removed as illustrated in FIG. 2, the fill port 38 is opened and held at a useful angle for one to pour washer fluid into the fill port 38. That washer fluid then flows down through the filler port wall 36 into the stringer section 22 of the fluid reservoir 18 where it can fill the stringer section and the finger sections 24 in communication therewith.

The plurality of finger sections 24 provided in the fluid reservoir may be shaped and oriented in an appropriate manner to minimize the generation of waves in the washer fluid so as to thereby reduce sloshing of the washer fluid in the fluid reservoir 18 during motor vehicle operation. Of course, if desired, it should be appreciated that baffles 48 of appropriate size and shape may be provided in the fluid retention cavity 26 along the stringer section 22 and/or along one or more of the finger sections 24 as illustrated in FIG. 1.

Reference is now made to FIGS. 3-6 illustrating various embodiments of the fluid reservoir 18. The embodiment illustrated in FIG. 3 is consistent with that illustrated in FIG. 1. In this embodiment, the fluid reservoir 18 includes a stringer section 22 that extends along or parallel to a longitudinal axis A1 of the hood assembly 10 from the front end 50 to the rear end 52. The plurality of finger sections 24 extend in a first direction from the stringer section 22 and are aligned with the lateral axis A2 of the hood assembly 10. Four finger sections 24 are illustrated in FIG. 3. It should be appreciated that fewer or more finger sections may be provided if desired.

In the embodiment illustrated in FIG. 4, the stringer section 22 extends laterally across the hood assembly 10 near the front end 50. Four finger sections 24 extend in a first direction from the stringer section 22. That direction is aligned with the longitudinal axis A1 of the hood assembly. In the embodiment illustrated in FIG. 4, there are four finger sections 22. It should be appreciated that a greater or smaller number of finger sections may be provided if desire and in order to better control washer fluid sloshing.

As illustrated in FIG. 5, the fluid reservoir 18 includes a body 20 with a stringer section 22, a first group 58 of finger sections 24 extending in a first direction from the stringer section and a second group 60 of finger sections extending in a second direction from the stringer section. In the illustrated embodiment, the stringer section 22 extends down the center of the hood assembly 10 along the longitudinal axis A1 while the finger sections 24 all extend laterally across the hood assembly parallel to the lateral axis A2. In this embodiment, the fill cap 40 extends through the hood shell 14 and may serve a dual function as a motor vehicle badge.

In the embodiment illustrated in FIG. 6, the fluid reservoir 18 includes a stringer section 22 that extends from the front left corner 62 toward the right rear corner 64 of the hood assembly 10. The first group 58 of finger sections 24 extends toward the front right corner 66 while the second group 60 of finger sections extends toward the left rear corner 68 of the hood assembly 10. In this embodiment, both the stringer section 22 and the finger sections 24 extend at a bias to the lateral axis 54 and the longitudinal axis 56.
